Golden Fishing Village

Finally, Ao Daguo went to get a magnifying glass. There was this thing in the cockpit. It is a traditional tool for ship driving. It was used to read sea charts in the past. Now there are electronic maps and GPS, but there are still magnifying glasses on the ship.

To the naked eye, the scales of the giant grouper are very smooth, and there is nothing special on them, but through a magnifying glass, you will find that there are black and white rings on the surface of the scales, just like the annual rings on the cross section of a tree.

Ao Qianpan said: "Just count the number of black rings on the scales, and add one, that is the actual age of the fish. For example, if there are three black circles on the scales, then the actual age of the fish is four years old."

Ao Wenchang was surprised and said: "It turns out that fish really have annual rings on their bodies."

Ao Qianpan was proud of himself for teaching a high-achieving student a lesson, Then he said with a smile: "Of course."

"I know why trees grow annual rings, but why do fish also grow annual rings?" Ao Wenchang asked curiously, "Uncle Qianpan, do you know the reason?"

This question stumped Ao Qianpan. He blinked and thought for a while, and finally said helplessly: "Anyway, it grows this thing, just like the growth of tree rings."

Ao Qianwen knew the reason and gave the answer with a smile: "Da Pan is right. The growth rings of fish scales are the same as the growth rings of trees. It is mainly the cyclical changes of nature year after year. This kind of fish scale is also called bone scale, which is evolved from the dermis of fish."

"In spring and summer, the water temperature is relatively high and the bait in the sea is rich. This is the peak growth season for fish. They grow fast, the fish skin develops fast, and the scales grow fast accordingly, so the rings between the rings are wider."

"In autumn and winter, As the water temperature drops and food decreases, won't the growth of fish slow down? In this way, the growth of scales must also slow down, and the rings between the circles are correspondingly narrower, so that annual rings appear. "

Ao Qianpan nodded and said, "Yes, Brother Wen is right. The wide and narrow annual rings on the scales represent a summer and a winter."

Ao Qianwen is an old driver at sea and knows a lot of things.

He said to Ao Muyang, "Don't think that fish don't talk. In fact, you can judge a lot of things about fish through observation. There are also several ways to infer the age of fish. Some methods are not applicable to certain fish, so you have to change to other methods. "

"The age of the fish can be inferred from the number of concentric circles on the scales. If the scales are not clear, you can also infer the age of the fish based on the spine, gill cover bones, dorsal fins, otoliths, etc., which is also useful. "

"For example, the vertebrae can be used to infer the age of flounder, and the salmon can be used to infer the age of salmon. The age can be estimated by looking at the operculum, the age of sharks can be estimated by looking at the fins, and the age of large and small yellow croakers can be estimated by looking at the otoliths. "

Hearing him say so much in one breath, Ao Muyang was very curious and asked, "How to estimate through these parts?"

Ao Qianwen said, "Same, these parts of these fish will also have the same growth rings, and the appearance is clearer."

Ao Muyang smiled and said, "Knowledge of the world is knowledge, and understanding of human nature is writing. We, the younger generation, still have a lot to learn."

When he said this, Ao Qianwen's face was bright.

But he still shook his head and said, "In fact, learning this thing is not very useful. Knowing more may not necessarily catch fish. It still depends on your ability, the leader."

Ao Wenchang carefully counted the number of black lines on the fish scales, a total of thirty-seven circles, which means that the fish is thirty-eight years old.

This grouper is not very big. After a night, they came back to collect the net. The fishing net was dragged in a mess, and there were a total of fourteen big fish hanging on it!

In addition, other fish were caught. This place is indeed rich in fish. There is even a yellowfin tuna hanging on it.

Catching tuna was unexpected but reasonable. The longline fishing they arranged was originally used to catch tuna.

In addition, there are other fish. Longline fishing has large hooks and small hooks. The large hooks are used to catch large fish such as tuna, while the small hooks can catch some small fish.

Among the giant groupers caught this time, the largest one is two meters and fifteen meters long. Ao Wenchang counted the number of circles on the scales, and there were a full forty-eight, which means that this fish is almost fifty years old!

After putting away the fishing net, they cast another net, but the harvest of this net was not big. No more giant groupers were caught on the net, only some common fish in the South China Sea such as sea catfish, bigeye snapper, and herring carp.

It has been four or five days since the last time they replenished fresh water on the island, and the Big Dragon Head needs to increase supplies again.

There is still some fresh water, but there is very little food and ingredients, so we need to find a transit station for replenishment.

The supply island chosen by Ao Daguo is Jinhou Island, which is one of the few inhabited islands in the South China Sea.

After sailing against the wind towards the north for a while, an island appeared in their sight.

This island is much larger than the small island they have visited before, with an area of ​​nearly one square kilometer. For the small islands scattered all over the South China Sea, this area is already very large.

From a distance, the island is covered with forests, like a green jade bead inlaid on the vast sea, which is extremely beautiful.

Compared with other sea areas, the ships here are lively. Many ships come to the island for replenishment, including fishing boats, yachts, transport ships and cargo ships, and even a warship.

Seeing the long and narrow warship slowly passing by, a group of people took out their mobile phones to take pictures.

Ao Muyang leaned over to look at the photos taken, and then shook his head: "What era is it, smart phones are everywhere, and you still take pictures with landlines?"

There is a pier extending out of the island. Ao Daguo docked the Dalongtou. He went to pay the berthing fee, and Ao Muyang took the others ashore.

Golden Monkey Island was originally called Jinshan Island. It is said that a fisherman saw a golden mountain from a distance on the sea and discovered the island after sailing there.

Later, about fifteen years ago, relevant state agencies found that the environment on the island was very suitable for raising monkeys, so they released more than ten macaques here. In just a few years, the group of macaques expanded and a race emerged.

Therefore, the island was renamed Golden Monkey Island. Today, there are not only macaques on the island, but also macaques, golden monkeys and other monkey species.

There are towns and residents on the island. It is the largest marine supply station in the surrounding area. The residents make a living by providing services to passing ships.

The small pier was bustling with people. When you walked out of the pier, there was a market with some fruits and non-staple food. The dark-skinned island residents waved enthusiastically:

"Authentic local coconuts, the water is so sweet, buy two and try them."

"Stinky tofu, old sausage, authentic delicacies flown from Shonan, delicious and affordable."

"Do you want accommodation? There are air conditioners, fans and ice-cold Coke. We have everything except the little girl. The wifi signal is absolutely full..."

There are many people selling things on the island, but the prices are not cheap. Ao Mubing went to ask about the price of coconuts, and they found that one cost 120 yuan.

Seeing this, several people were stunned: "Forget it, let's go find a restaurant to drink cold water. The price is simply a rip-off!"
